Albert King "The Velvet Bulldozer" and one of the "Three Kings of the Blues Guitar" (along with BB and Freddie) he recorded dozens of influential songs, such as 'Crosscut Saw' and 'As The Years Go Passing By', and the 1967 album, 'Born Under a Bad Sign.'
Guitarists have copied his licks for decades. Cream famously covered the title song 'Born Under a Bad Sign.' on 1968 'Wheels Of Fire' album, and Eric Clapton was said to have been inspired to write Layla after 'Years Go Passing By'. Clapton later said the 1967 Cream album 'Disraeli Gears' and the song 'Strange Brew' was inspired by King.
King is mainly associated with a Gibson Flying V which he began 1956. He was left-handed, but usually played right-handed guitars upside-down. He used a dropped minor tuning, reportedly C-G-B-E-G-C (but he never used the sixth string).
He gave the guitar to his adopted "cousin" Lee King just a few days before he passed away in December 1992.
For amplification, King used a solid-state Acoustic amplifier, with a speaker cabinet with two 15" speakers and a horn ("which may or may not have been operative"). Later in his career he also used a MXR Phase 90.
Here he is playing 'Blues Power' around 1971.
